Definitions

  • the invention relates to a wall heater consisting of a circuit board arranged in a housing as a carrier for the burner with accessories and for the hydraulic components.
  • Such wall heaters that are used for heating and hot water supply are determined by smaller residential units in particular, are well known and in use, so in this regard no special printed evidence is required.
  • Burner with accessories and the hydraulic components so tight summarized as possible in the smallest space in the enclosure arranged on a flat circuit board the must be dimensioned sufficiently stable, unless special Support frames are provided for wall mounting what is also practiced. Under “Burners with accessories” are to understand here the burner with downstream combustion chamber, Exhaust gas heat exchanger and exhaust gas collector.
  • Such wall heaters have proven to be capable of improvement, in the direction of use as low as possible Material thicknesses for the board and this at least comparably good stability, convenient handling series production assembly, maintenance and any exchange requirements and also taking into account the one such a requirement of a sufficient Suspension stability as a carrier for all components serving board, connected to the further stipulation, in the manufacture of the wall heater either for Establish a room air-dependent or room air-independent mode of operation to be able to.
  • This task is with a wall heater of the type mentioned kind solved according to the invention in that the carrier about midway up the enclosure to the front of the enclosure in the form of a cranked Stage is formed which is parallel to the plane of the support surface has a cranked mounting bracket, the such stepped and cranked straps between laterally Crimped parts in front of the enclosure housing Cladding sheet metal is integrated and also support surface, Step and mounting bracket with stiffening edge bends are provided.
  • the mounting bracket is in the form of two on the side areas the stage attached mounting tabs formed between those of the carrier, also parallel to the carrier surface, with a downward-facing mounting bracket is provided.
  • the wall baths both for Indoor air-dependent as well as indoor air-independent operating modes can be created.
  • For an operation independent of the ambient air is only between the mounting brackets and to arrange an air duct box for all burner components, with due regard to assembly and accessibility is advantageously in the form of two shells, namely in such a way that the air guide shell provided with a trigger passage in a vertical section u-shaped and the other bowl is also U-shaped in horizontal section and both shells sealed against each other by quick fasteners are interconnected.
  • the step in the carrier is with a slot for one provided the bottom of an expansion tank and this advantageous in connection with the fact that the upper ends of the two side cladding panels with a sheet metal crossbar are connected, which also has a receiving slot for the upper edge of the expansion vessel is provided.
  • the burner and its associated components are also shown in a carrier detachably connected to the mounting brackets arranged, which in turn in an advantageous embodiment Form of a U-shaped in vertical section, with trigger opening provided bowl and this one in horizontal section also releasably assigned to a U-shaped cover shell is.
  • the wall heater according to the invention is described below with the aid of graphic representation of exemplary embodiments explained, which are all shown in perspective.
  • the wall heater consists in a known manner of a circuit board arranged in an enclosure 1, 1 ' as a support 2 for the burner B with accessories and for the hydraulic components.
  • the stage 3 is also advantageously provided with a receiving slot 8 for the lower edge of an expansion vessel AD, and further (see Fig. 3) in this context the upper ends 6 'of the two side cladding panels 6 are connected to a sheet metal traverse 9, which is also with a receiving slot 8 'is provided for the upper edge of the expansion vessel AD.
  • the combustion chamber is for an air-dependent operation K to the associated exhaust heat exchanger AWT Mounting brackets 4 'and the burner B on the mounting bracket 5 releasably attached.
  • both shells 10, 12 an air guide box form.
  • the air guide shell 10 provided with trigger passage 11 in a vertical section u-shaped and the cover 12 in Horizontal section also U-shaped, and both Shells 10, 12 are against each other by quick fasteners (not shown) sealed together.
  • the burner B shown in FIG. 4 with its components only for the sake of completeness is arranged on a support 10 detachably connected to the mounting brackets 4 'of the support 2 provided with step 3, wherein, as mentioned above, this support 10 is preferably in the form of a vertical section U-shaped shell 10 'is formed, to which the horizontal U-shaped cover shell 12 is releasably assigned.
  • This unit which represents, for example, a separately mountable burner module, also includes an AWT exhaust gas heat exchanger, with which an apartment heating unit is supplied.
  • the carrier 10 receiving the burner B is dimensioned and arranged on the mounting brackets 4 'of the bracket 2 such that the entire area of the bracket 2 below the step 3 or the mounting bracket 5 remains free for the hydraulic components arranged there, of which with P is a circulation pump and BWT is a process water heat exchanger.
  • the hydraulic connections are essentially located on the rear side of the carrier surface F, which is provided with corresponding through openings and connections for this purpose, which does not require any further explanation in detail, since nothing changes in the previously customary design of such connections.
  • the two side panels are 6 assigned to the carrier 2 such that between the rear edges 6 '' of the cladding panels 6 and Carrier surface F sufficient space for the arrangement of Connection lines (return piping) available stands.
  • 1, 2 and 3 correspond in practice to the process of final assembly of such a wall heater, that is, the punched and cranked support 2 shown in FIG. 2 is equipped as far as possible with appropriate connection fittings (preferably quick plug connections) and with Completed the two cladding sheets 6 to form an independently stable base body (chassis), after which the hydraulic components were installed, connected and connected on the front and rear. Thereafter, only the whole of the basic body of the wall heater, which has become stable and stable in itself, is easily accessible for all further assembly processes, i.e.
  • the burner module is attached from the front and attached to the mounting brackets 4 ', 5, the expansion vessel AD is inserted from above and with the Sheet metal traverse 9 is fixed and, finally, after the cover shell 12 has been pushed open for the burner module and the production of all connection and line connections, the whole has to be completed with the front part 1 'of the housing enclosure.
  • the exhaust manifold acts a collection box when operating in a room-air-dependent manner with exhaust connection 13 with for atmospheric Burner B of the usual type and with room air independent Operation of the wall heater around a collecting box with induced draft fan (top right in Fig. 4), here essential is that both types of header boxes on the one hand to the exhaust gas heat exchanger AWT and on the other hand towards the exhaust connection have appropriate connection dimensions.
  • the exhaust collector AS with fan G thus comes in the embodiment of 3 for use, i.e., within the Air duct box LK.
  • FIG. 3 is used for the actual wall fastening in FIG shown holding strip HL, on the hook of which the side Cladding sheets 6 with their corresponding holes provided, cranked edges can be hung.
  • FIG. 5 provides a clear overview the hydraulic piping and the other one in this regard advantageous embodiment, as here by a Channel distributor housing 100 reduces the piping effort is.
  • 5 are denoted by 101 in FIG Heating flow, with 102 the hot water flow, with 103 the Heating return, with 104 the supply line to the exhaust gas heat exchanger AWT, with 105 a water switch for the hot water requirement, with 106 a switching valve heating / domestic water, with 107 a vent valve, with 108 the outlet from Exhaust gas heat exchanger AWT and 109 to switch valve 106 belonging channel distributor.
  • Hydraulic elements are double-walled according to the ducting Channels pressed board are provided, although quite also the surface F of the carrier 2 itself a layer one could form such a board.
